Wow, only 30 days these days? Iirc when cambridge analytica fiasco it need 90 days to fully deleted facebook account. I did mine tho. I download all my facebook data, they gave me link of zip item that if u extract it look like full page html old facebook look like. After i download all my data i delete my account for good. And few months ago i create an account with all fake info mail name etc just to access fb marketplace. Somehow i need it to find some stuff nearby.
